Abstrakt: Developmental aspects of behavioral organization were investigated in 29 healthy fetuses from 24-weeks gestation onwards: (a) short-term association between body (GM) and eye (EM) movements; (b) linkage of pairs of the three state variables [fetal heart rate pattern (FHRP), GM, and EM]; and (c) sequence of change of state variables during transitions. Linkage and sequence were also studied in complicated pregnancies. Short-term association between GM and EM was well established after 28 weeks. Linkage of state variables improved considerably after 32–34 weeks. FHRP was the first variable to change during synchronized transitions from 1F to 2F between 28–39 weeks, and the last variable during 2F to 1F transitions between 32–39 weeks. Although clear developmental patterns could be recognized, the interfetal variability was such that identification of the abnormal fetus is still difficult. Only transitions were significantly different in growth-restricted fetuses, as they showed no specific sequence of change. Assessing the temporal organization of fetal behavior seems, therefore, until now, not of great clinical value. © 1999 John Wiley & Sons, Inc. Dev Psychobiol 34: 257–268, 1999 [ABSTRACT FROM AUTHOR]
